摘要:
The aim is to provide a flame retardant for thermoplastic resins that has a high flame-retardant imparting effect, and that produces a thermoplastic resin composition with superior moldability and workability that does not easily bleed out and a molded body with superior resistance to heat-moisture and chemicals; and a flame retardant for thermoplastic resins that has a high flame-retardant imparting effect, and that produces a flame retardant with a heat resistance to working temperatures of 300° C. or higher and a molded body with superior resistance to reflow heat and chemicals. Disclosed is a flame retardant, which is a specific flame retardant for thermoplastic resins comprising the reaction product of a nitrogen-containing compound and a phosphorous-containing compound, that is insoluble in toluene and comprises in the range of 5 to 10 wt % of phosphorus atoms. The aforementioned flame retardant may have a weight average molecular weight (Mw) in the range of 2,000 to 10,000, or may have a ratio of at least 1 wt % of crosslinking components within the flame retardant components.

A key data recording device includes a key data recording medium section which stores key data of the encrypted data; and a reading/writing section which reads and writes the key data from and into the key data recording medium section, which sections are contained in a cartridge casing accommodatable in a library unit. When the cartridge casing is irregularly ejected from the library unit, the key data recorded in the key data recording medium section is deleted. This configuration can enhance the confidentiality of encrypted data because the key data is not leaked even when the recording medium in which key data of the encrypted data is recorded is carried away.

摘要:
A press-forming device has a punch (2), a die (7) which relatively moves with respect to the punch (2), a strain amount measuring means (8) which is provided inside a member to be controlled and measures a strain amount of the aforesaid member to be controlled which occurs in accordance with press-forming, when at least one of the punch (2) and the die (7) is made the aforesaid member to be controlled, and a strain amount control means (9) which is provided in the aforesaid member to be controlled and controls the strain amount of the aforesaid member to be controlled which occurs in accordance with press-forming. The strain amount control means (9) controls a drive amount of the aforesaid member to be controlled so that the strain amount measured by the strain amount measuring means (8) is in a predetermined range during forming. Thereby, reduction in a surface strain, improvement in shape fixability or the like of a press formed product can be achieved.

A system, method and software arrangement are provided for generating press-formed parts having a more consistent quality based on improved determination of processing conditions. For example, an apparatus can be configured to compare actual performance values of material properties provided by a material property database with standard values, and to adjust forming conditions such as a forming speed and a blank-holder pressure in accordance with the compared result. A control arrangement can be provided to control a press-forming device using the adjusted forming conditions. Accordingly, it may be possible to reduce occurrences of defects such as cracks and wrinkles when press-forming materials, and to obtain products having consistent quality and substantially identical shapes.

A removable hard disk drive is detachable from a computer apparatus, and includes a storage medium for storing data from the computer apparatus and a communication interface with the computer apparatus. Upon reception of eject instruction issued by the computer apparatus, the removable hard disk drive writes contents cashed in a cache memory into a disk, and shifts to an ejectable state. Upon the completion of the shift to the ejectable state, the removable hard disk drive externally outputs an eject signal. A microprocessor which controls an eject mechanism executes removable hard disk cartridge eject operation in response to the eject signal.
